A landing gear mechanism is shown in the accompanying figure. You may assume that it is in static equilibrium in the configuration shown. You may neglect all of the weight except that of the strut and wheel (225 lb) which is located at point G. The force F, applied to member BCD, drives the retraction. Find: a. The force in link AB. (Hint: Use a coordinate system aligned with the wheel strut.) b. The magnitude of the pin force at the pin at P. c. The force F required for static equilibrium. (Hint: Now a use a coordinate system aligned with the BC axis.)

What is static force analysis? A four bar mechanism has following dimensions: Length of crank=100 mm, Length of coupler link=450mm, length of rocker-270 mm and length of fixed link=250 mm. A force.F=-100i N is applied on to mid-point 'C' of rocker, when crank makes 120° from positive x-axis. Calculate pin forces and torque to be applied on to the crank for equilibrium. 1. A disturbing mass 'm' kg is attached to a shaft. The shaft is rotating at 'n' rpm, The radial distance of the center of gravity of the disturbing mass from the axis of rotation is 'r' mm. It is required that the disturbing mass should not be disturbed by any addition or subtraction of mass. Suggest the ways to balance the system and justify by proper expressions. 2.

O₁ and O₂ are the fixed link in the mechanism which is 3.25" away from each other in a vertical orientation (O₁ at the top). At the end of the 1.125" crank (O₁A) is a slider that is pin connected at A and sliding at 7" link O₂B. Link O₂B is pinned-connected to link BC, 3" long and BC is pinned-connected to another slider at point C and translating in a horizontal direction. From the given problem, determine the type of mechanism and the limiting travel distance of the Slider connected at point C. Use the analytical method in solving the problem. Note: The distance of the slider C axis from O₂ is 7".

3. Figure 3 shows a brake pedal assembly from a car. Under the action of an applied foot force, the pedal lever acts against the fixed pivot and transfers load to the brake cylinder via an actuation rod. The pedal lever is of hollow section, three-sided form with section dimensions as shown in the figure (Section A-A). Via consideration of the pedal lever as a free body, calculate the reactions acting at the fixed pivot and the 10 mm dia. pin.
